Taking a Different Approach to Rare Epilepsies

Lennox-Gastaut syndrome and Dravet syndrome are two rare, developmental and epileptic encephalopathies. Drug developers have sought to address epilepsies by altering the electrical activity in the brain. Ovid therapeutics, though, has taken a novel approach with its experimental therapy soticlestat by seeking to restore homeostasis to the brain. We spoke to Meg Alexander, chief strategy officer of Ovid, about rare epilepsies, how the company’s experimental therapy soticlestat works, and the potential to apply the approach to other CNS conditions. Since recording this episode, there have been new results on soticlestat released. Ovid’s partner Takeda this week reported that soticlestat narrowly missed its primary endpoint in its phase 3 Dravet syndrome study while showing clinically meaningful and nominally significant effects in multiple key secondary efficacy endpoints. It also missed its primary endpoint of reduction in major motor drop seizures as compared to placebo in a separate phase 3 study in Lennox-Gastaut syndrome. Takeda said it will be engaging with regulators to determine the best path forward.
